<p>A device which can provide tap water at some specified temperature simply by turning on a hot water knob and a cold water knob. By turning a calibration dial, a control pin can be turned accordingly by which the degree of alignment of a pair of control holes with respect to a pair of spiral grooves is adjusted and a specified temperature of water is obtained. Therefore, once the calibration dial is set, a certain temperature of water can be obtained every time by simply turning on the water knobs and without having to readjust the knobs several times before reaching some desired temperature of water.</p> |
